Educación nutricional para el fortalecimiento de la calidad de vida en adultos mayores

The adoption of healthy habits regarding food can be considered a necessity at any stage of life. However, this conviction is more significant when it comes to boosting the quality of life in older adults who require more attention regarding the form and content of their diet. In this sense, it is clear that, when related to health, quality of life acquires a comprehensive perspective where individual well-being is related, both to personal care when eating or acquiring healthy lifestyle practices, as with the establishment of relationships in the environment in which individuals operate. From this perspective, this article aimed to interpret the relevance of educational strategies to promote nutritional habits that favor the quality of life of older adults in an Ecuadorian town. From the point of view of methodology, an approach was carried out from the mixed approach, which involved, at first, a hermeneutics of the theories and approaches that relate nutritional education to quality of life. Subsequently, the results of a questionnaire on nutritional education are analyzed, aimed at a sample of older adults who live in the context under study, to assess their knowledge regarding nutritional education in relation to their quality of life. Finally, it can be confirmed that older adults' nutritional education level guides them in adopting eating habits that can improve their quality of life.

Moringa Reduces Glucose Levels and Alters Wolbachia Abundance in Drosophila melanogaster

Moringa oleifera Lam. (moringa) is a plant native to India, used as a nutritional and medicinal supplement in many cultures around the world. Moringa has been linked to maintaining metabolic homeostasis and is often marketed as a weight loss supplement and a potential remedy for diseases such as diabetes. Here, we investigate how moringa, a ‘superfood’ with predicted protective effects against chronic diseases such as diabetes, influences the nutritional physiology and microbiome composition of the fruit fly Drosophila melanogaster. We administered moringa as a dietary supplement to Drosophila, and quantified key nutritional indices: glucose, triacylglyceride, and protein levels, and fly weight. We showed that dietary moringa supplementation significantly reduced fly glucose levels by up to ~30% and resulted in substantial restructuring of Drosophila microbiota composition, altering both gut and intracellular bacterial populations. The effect of moringa on fly glucose levels is specific because other nutritional indices, namely, triacylglyceride and protein levels and fly weight, were not significantly affected by dietary moringa supplementation. This study highlights the importance of moringa as a modulator of host glucose metabolism.

Incidence and Risk Factors for Perioperative Pressure Injuries: Prospective Descriptive Study

PurposePressure injuries can often occur in patients undergoing surgical, diagnostic, or other invasive procedures, so it is important to assess patients in the perioperative period. This study was conducted to determine the incidence and risk factors of perioperative pressure injury. DesignA cross-sectional, prospective, and descriptive study. MethodsThis study involved 158 patients who met the study's eligibility criteria between May 2022 and July 2022. The data were collected using the Patient Information Form, Munro Scale, Braden Scale, and pressure injury staging form. The patients were monitored postoperatively or for 3 days. FindingsPressure injury developed in 13.9% of the patients. Perioperative risk factors were age, edema, mobilization time, parenteral nutrition, blood transfusion, and glucose level, while preoperative albumin level was lower in patients with pressure injury. In the postoperative period, the risk factors were duration of mobilization and transition to oral feeding, length of intensive care unit stay, and low Braden score. In multivariate analysis, the variables that showed significance with the risk of pressure injury were postoperative Munro score and edema. ConclusionsIt is crucial to evaluate the risk factors for pressure injury in patients who have undergone surgical procedures.

Risk factors of poor nutrition in non-small cell lung cancer patients after chemotherapy: cross-sectional study

This cross-sectional study aimed to analyze the associated factors of poor nutrition in non-small cell lung cancer (NSCLC) patients after chemotherapy. Concretely, 176 NSCLC patients who attended our hospital from June 2020 to December 2022 were enrolled. Standard-compliant patients were categorized into nutrition group (n = 38) and malnutrition group (n = 70) according to different nutrition statuses. Baseline characteristics and nutrition level were assessed. Associated factors of poor nutrition were analyzed by logistic regression analysis. There were obvious differences between nutrition group and malnutrition group in terms of age (P = 0.041), body mass index (BMI, p = 0.021), residence (P = 0.023), per capita monthly income of family (P = 0.023), tumor staging (P = 0.017), Karnofsky (KPS) score (P < 0.001), effect of chemotherapy (P = 0.045), and nutrition support before chemotherapy only (P = 0.023) and perichemotherapy (P = 0.011). The higher proportion of NSCLC patients was found in malnutrition group relative to nutrition group in terms of having poor nutritional cognition (67.14% vs. 47.37%, P = 0.045), and lacking access to vitamins (65.71% vs. 44.74%, P = 0.047) and trace elements (57.14% vs. 36.84%, P = 0.044). BMI <18.5 (OR = 3.707, P = 0.007, 95%CI (1.434–9.586)), residence in village (OR = 3.426, P = 0.013, 95%CI (1.291–9.092)), and KPS score ≤70 (OR = 7.608, P < 0.001, 95%CI (2.842–20.367)) were associated factors for poor nutrition. Collectively, BMI, residence, and KPS score were associated factors of poor nutrition in NSCLC patients after chemotherapy.

The Effect of Parents' Nutrition Literacy on Children's Oral-Health-Related Quality of Life.

Parents can help children adopt good eating habits early in childhood by encouraging them to eat healthy. While parents' levels of nutritional literacy is known to play a role in children's healthy nutrition, healthy food is also essential in improving oral-health-related quality of life (OHRQoL). Since the effect of parents' nutritional literacy on children's OHRQoL is not yet known, this study aimed to examine the impact of parental nutritional literacy on children's OHRQoL. This study was conducted with 459 parents of children aged 3-6 living in the Central Anatolia Region of Türkiye. Data collection tools included a sociodemographic form, the Early Childhood Oral Health Impact Scale (ECOHIS) and the Evaluation Instrument of Nutrition Literacy on Adults (EINLA). Data were analyzed in SPSS, using Student's t-test, Chi-square test, and binary logistic regression models. Parents with higher nutritional literacy tend to have higher levels of education. An increase in total nutritional literacy score, especially in the general nutrition knowledge (GNK) and food label and numerical literacy (FLNL) subscales, was associated with higher child OHRQoL. Increasing parents' nutritional literacy levels can contribute to OHRQoL by enabling them to be good role models for their children. Therefore, increasing parents' nutritional literacy can improve OHRQoL by improving children's nutrition and can be considered a protective factor for oral health.

Correlation of Co-Morbidities with Symptom Severity of Children with Autism Spectrum Disorder: A Cross-Sectional Survey.

This study aims to identify potential correlations of the severity of symptoms of children with autism spectrum disorder (ASD) with serum nutritional levels, body composition indicators, diet partiality, and sleep disturbances. The cohort of this cross-sectional study included 120 children with ASD and 110 typically developing (TD) children to assess symptoms of ASD, and to measure serum levels of vitamins and minerals and the body composition values. Diet partiality and sleep disturbances were assessed by administering questionnaires. The serum levels of folic acid, copper, and vitamin B were lower in children with ASD than in TD children, while magnesium and homocysteine were higher (p < 0.05). Children with ASD had greater chest circumference, abdominal skinfold thickness, and body mass index (BMI) than TD children (p < 0.05), and higher prevalences of diet partiality and sleep disturbances (p < 0.001). Lower vitamin A levels and higher vitamin D levels were related to social impairment in children with ASD. Moreover, there were significantly positive correlations of BMI, chest circumference, diet partiality, and sleep disturbances with severity of ASD symptoms (p < 0.05). Collectively, rational nutritional supplementation, dietary management, and behavioral interventions are essential for children with ASD.

The long-term nitrogen fertilizer management strategy based on straw return can improve the productivity of wheat-maize rotation system and reduce carbon emissions by increasing soil carbon and nitrogen sequestration

ProblemFacing the multiple objectives of increasing production, carbon sequestration, and nitrogen reduction in farmland, optimizing straw and nitrogen fertilizer management to achieve a balance between grain production and ecological safety in the wheat-maize rotation system has become increasingly critical and urgent. MethodsThis study conducted a five-year field experiment in the Guanzhong Plain of China from 2017 to 2021 to investigate the effects and synergistic regulatory mechanisms of straw disposal methods (straw return, no-straw return) and nitrogen application rates (0, 150, 225, 300 kg ha−1) during the maize season on soil greenhouse gas (GHG) emissions, crop yield, and soil organic carbon (SOC) and soil toatl nitrogen (STN) content. ResultsThe results showed that under the scenario of no-straw return, fertilization increased soil nitrous oxide (N2O) emissions by 35.9–64.0 %, and annual total crop yield by 16.4–22.8 %; however, under the straw return scenario, the increase in soil N2O emissions due to fertilization decreased to 26.7–62.0 %, while the yield increase rose to 19.5–25.9 %. The interaction effect between straw return and nitrogen application was significant, with straw return boosting the contribution rate of nitrogen application to yield (2.2–4.4 %) and simultaneously reducing the contribution rate of nitrogen application to N2O emissions (3.0–27.5 %). The study also indicated that the yield-increasing effect of straw return continued to increase with the duration of straw return, with the contribution rate to yield reaching 9.9 % after three years of continuous straw return, while the contribution rate of nitrogen application to yield increased by an average of 3.0 % per year. This suggests that there is significant potential for coupling straw return with reduced nitrogen application. Straw return combined with nitrogen fertilizer increased SOC content by 7.9–40.1 % and 3.7–12.5 %, STN content by 1.0–22.8 % and 6.1–13.9 %, respectively, compared to sole nitrogen application and sole straw return. Pathway analysis indicated that straw return combined with nitrogen fertilizer mainly enhanced soil carbon-nitrogen sequestration, improved fertilizer utilization efficiency and crop nutrition levels, reduced net global warming potential (GWP) and greenhouse gas intensity (GHGI), and synergistically regulated to increase yield while reducing GHG emissions. ConclusionThe study highlights that straw return lowers the threshold for nitrogen application levels, suggesting that regulating nitrogen application levels between 224 and 256 kg ha−1 during the maize season, and maintaining a nitrogen application level of 195 kg ha−1 during the wheat season, is beneficial for long-term stable production and emission reduction in the wheat-maize rotation system farmland.

Impact of ultra-early enteral nutrition support on the prognosis of young and middle-aged postoperative patients with cerebral hemorrhage

To investigate the effect of ultra-early enteral nutrition (UEEN) support on the prognosis of young and middle-aged postoperative patients with cerebral hemorrhage. The clinical data of young and middle-aged patients (aged 18-59 years) admitted to Tianjin Fifth Central Hospital from January 2020 to June 2023 after surgery for intracerebral hemorrhage were retrospectively analyzed, and the general data, nutritional indexes, gastrointestinal complications, neurological function recovery and long-term prognosis of the patients were recorded. According to the time of initiation of enteral nutrition (EN) support, patients were divided into UEEN group (EN implementation within 12 hour after surgery) and early enteral nutrition (EEN) group (EN implementation within 24 to 48 hour after surgery). The differences of the above indexes between the two groups were analyzed and compared. A total of 64 young and middle-aged postoperative patients with cerebral hemorrhage were enrolled, including 32 cases in the UEEN group and 32 cases in the EEN group. There were no significant differences in gender, age, proportion of hypertension and diabetes, Glasgow coma score (GCS) on admission and surgical methods between the two groups. In terms of nutritional indexes, serum total protein, albumin and hemoglobin levels of patients in both groups on day 7 after admission were lower than those on day 1, and higher than those on day 3, and the above indexes levels in UEEN group were significantly higher than those in EEN group on day 7 [total protein (g/L): 63.05±5.79 vs. 59.02±6.63, albumin (g/L): 40.40±5.26 vs. 37.66±4.63, hemoglobin (g/L): 133.33±12.58 vs. 123.80±22.12, all P < 0.05]. In terms of gastrointestinal complications, the incidence of stress ulcer in the UEEN group within 14 days after admission was significantly lower than that in the EEN group [12.5% (4/32) vs. 31.3% (10/32), P < 0.05], but there was no statistically significant difference in feeding intolerance symptoms between the two groups. In terms of neurological recovery and long-term prognosis, GCS scores and Barthel index scores of 14 days after admission were higher than those of 1 day after admission, but there was no statistical significance between the two groups. Six months after surgery, Glasgow outcome scale (GOS) and Barthel index score of the UEEN group were significantly higher than those of the EEN group (GOS score: 3.81±1.06 vs. 3.18±1.07, Barthel index score: 60.78±7.24 vs. 54.52±5.13, both P < 0.05). UEEN support can improve the nutritional level of young and middle-aged postoperative patients with cerebral hemorrhage, reduce the occurrence of postoperative gastrointestinal complications, promote the recovery of neurological function, and improve the long-term prognosis.

Influence of Liquid Nitrogen Pre-Freezing and Drying Methods on the Collagen Content, Physical Properties, and Flavor of Fish Swim Bladder.

Fish swim bladder (FSB) is a type of traditional nutraceutical, but the lack of high-quality drying methods limits its premium market development. In order to obtain optimal-quality dried FSBs from Chinese longsnout catfish, the effects of liquid nitrogen pre-freezing (LNF) and drying on the physical properties and flavor of FSB were evaluated. Four methods were used for FSB drying, including natural air-drying (ND), hot-air-drying (HD), LNF combined with freeze-drying (LN-FD), and LNF combined with HD (LN-HD). Color, collagen content, rehydration ratio, textural properties, and flavor characteristics (by GC-IMS, E-nose, and E-tongue) were measured to clarify the differences among four dried FSBs. The results showed that ND cannot effectively remove moisture from FSB as the final product showed a stronger sourness in taste. HD led to a decrease in the collagen content and the collapse of the fiber structure in FSB. Compared to HD, LN-HD showed a higher collagen content (0.56 g/g) and a different flavor fingerprint. FSB treated by LN-FD had better physical qualities in terms of an attractive color, a high collagen content (0.79 g/g), low shrinkage, a higher rehydration ratio (2.85), and a soft texture, while also possessing richer characteristic flavors. The application of LN-FD may help the optimization of the nutrition level, rehydration ability, mouthfeel, and flavor of dried FSB.

Assessing the risk factors associated with nutritional status in patients with liver cirrhosis: A case-control study.

Cirrhosis is one of the most common clinical diseases in the world. The patient with cirrhosis has many complications, such as spontaneous peritonitis, hepatic encephalopathy. Malnutrition is one of the most common complications in patients with cirrhosis, and it is also a key factor affecting the prognosis of patients. However, the research on cirrhosis malnutrition is relatively scarce. This study aimed to explore the new factors of the liver cirrhosis with the nutritional status. A total of 370 patients with liver cirrhosis were admitted to the Fourth Affiliated Hospital of Harbin Medical University from January 2019 to January 2023 were selected. Patients were assigned to the malnourished group and normal group. The weight, height, mid arm circumference (MAC) and triceps skinfold thickness (TSF) of the two groups were measured. Body mass index (BMI) and mid-arm muscle circumference (MAMC) were calculated. Furthermore, the Health Literacy Management Scale (HeLMS), biochemical indexes, incidence of complications, disease grade were also counted and the Royal Free Hospital-Nutrition Prioritization Tool were used to evaluate the nutritional status of the patient. A total of 370 patients was included in this study, including 177 malnutrition patients, accounting for 45.29%, and the scores and total scores of the patients in the malnutrition group were lower than those in the normal group. The measured values of Na+, Alb, PA, T-Bil, TC, TLC, Hb, and RBC were all lower than those of the normal group, and the difference was statistically significant. The overall complication rate of the patients in the malnourished group was 89.61%, and that of the normal group was 39.78%. Multifactorial logistic regression analysis was performed with nutritional level as the dependent variable (normal = 0, malnutrition = 1), and the above indicators of variability (Na+, Alb, PA, T-Bil, TC, PT, Hb, RBC, HG, and HeLMS scores) as the independent variables. The results showed that Na+, Hb were the influencing factors of nutritional level (P< 0.05). The incidence of malnutrition in cirrhotic patients included in this study was at a moderate level, and the nutritional literacy of these patients was low. In addition, the level of serum sodium, Hemoglobin can affect the nutritional level of patients with cirrhosis.

Exploring HLA-C methylation patterns and nutritional status in Kichwa mothers and infants from Tena, Ecuador.

Environment and lifestyle can affect the epigenome passed down from generation to generation. A mother's nutrition can impact the methylation levels of her offspring's epigenome, but it's unclear which genes may be affected by malnutrition during gestation or early development. In this study, we examined the levels of methylated GC in the promoter region of HLA-C in mothers and infants from the Kichwa community in Ecuador. To do this, we analyzed saliva samples using bisulfite DNA sequencing. While we did not observe any significant differences in the mean methylation percentages in exon 1 of HLA-C between mothers and their infants after the first two years of lactation and life, respectively, we did find that infants tended to increase their methylation level during the first two years of life, while mothers tended to decrease it after the first two years of breastfeeding. When we compared methylation levels between mothers and infants using an ANOVA/posthoc Tukey test, we found that the average methylation for the entire population was less than 3% at T1 and T2. Although there was a tendency for infants to have higher methylation levels during their first two years of life and for mothers to have lower methylation levels after the first two years of breastfeeding, the mean values were not significantly different. However, we found a significant difference when we contrasted the data using a Kruskal-Wallis test at 0.05 for T1 AND T2 (p-value: 0.0148). Specifically, mothers had an average of X̅ = 2.06% and sons had X̅ = 1.57% at T2 (p-value: 0.7227), while the average for mothers was X̅ = 1.83% and for sons X̅ =1.77%. Finally, we identified three CpG motif nucleotide positions (32-33, 43-44, and 96-97) along the 122 bp analysis of HLA-C exon one, which was found to retain methylation patterns over time and is inherited from mother to offspring. Finally, our small pilot study did not reveal significant correlations between maternal and offspring nutritional status and DNA methylation levels of HLA-C exon one.

Physicochemical Characterization of Carao Honey Flour (Cassia grandis) and Its Effects on the Sensory Attributes in a Cookie

Carao honey is a potential functional ingredient that can generate added value to food products enriched by reducing waste. In many countries, carao has been utilized for therapeutic purposes since this type of plant extract can inhibit the growth against the most common dermatophytes, a pathogenic fungus that grows on the skin, mucous membranes, hair, nails, feathers, and other body surfaces, causing ringworm and related diseases. The physicochemical characteristics of the cookies were also investigated, which included aW, proximate analysis, hardness, and color. A sensory study was carried out to determine the rejection threshold, acceptability, purchase intent, and general taste of 90 consumers. The gluten-free cookies were prepared with carao honey as a partial substitute for rice flour in different percentages (0%, 2.5%, 5%, and 10%). The carao honey proximate composition, rheological properties, and pasting properties were analyzed. It was emphasized that incorporating carao honey into cookies improves the ingredient’s sustainability. The impact of carao on the physicochemical and sensory properties of cookies was evident in color, flavor, and smell. According to the results, only samples with 2.5% carao were accepted regarding flavor and smell. Overall, liking scores, age, and flavor were the most significant predictors of purchase intent. The information given to panelists did not significantly (p &lt; 0.05) influence liking scores only for cookies. According to physicochemical analysis, carao honey flour was high in carbohydrates (88%). The incorporation of carao produced cookies with darker colors and a softer texture. The study demonstrated that carao flour could be included to produce sensorial accepted cookies at a 2.5% addition level as an alternative in the food industry that benefits from environmental sustainability and, at the nutritional level, improves the availability of nutrients, mainly sugars and proteins.

Comparison of Nonlinear Functions to Define the Growth in Intensive Feedlot System with XGBoost Algorithm

The aim of this study was to define the growth by using nonlinear functions in intensive feedlot system with XGBoost algorithm. To achieve this aim, five nonlinear functions were implemented. To implementation of the study, Brown Swiss (n=41) and Simental (n=95) breed were used. Each nonlinear functions were examined for each breed. According to the results of the nonlinear functions, logistic model was the best prediction model for defining the growth of each breed. In this study, the parameters in the best prediction model were calculated individually and the relationship of these parameters with body weight was evaluated with the XGBoost algorithm. Model comparison criteria such as standard deviation ratio (SDratio), Pearson’s correlation coefficient (PC), determination of coefficient (R2) and Akaike’s information criteria (AIC) were used to evaluate the XGBoost algorithm. In conclusion, the XGBoost algorithm can be an effective and optional approach that allows breeders to estimate live weight from growth parameters. This algorithm can operate on large data sets with high accuracy and speed, leading to significant improvements in agricultural productivity and animal health management. XGBoost enables more accurate predictions by analyzing the effects of various characteristics (e.g., nutritional level, breed, age). Therefore, this method can be used to determine critical parameters such as body weight in animal breeding practices, serving as a powerful support tool for operational decisions.

Response of oilseed flax to different level of mineral nutrition in the forest-steppe of Western Siberia

The article presents the results of studying the influence of nitrogen and phosphorus fertilizers on the water regime of meadow-chernozem soil, yield and oil content of flax seeds in 2022–2023. on a stationary experiment at the field forage production laboratory of the Federal State Budgetary Institution “Omsk ASC” in the conditions of the southern forest-steppe of the Omsk region. The objects of observation are oilseed flax of the Northern variety and meado-chernozem soil. The scheme of the experiment included the following options: factor A — medium soil availability of mobile phosphorus (50-100 mg/kg according to F.V. Chirikov, background 0), increased (100–120 mg/kg, background I and 140–150 mg/kg, background II), high (150– 200 mg/kg, background III); factor B — phosphorus fertilizer (P0, P60); factor C — nitrogen fertilizer (N0, N30, N60). In this case, nitrogen and phosphorus fertilizers were superimposed on backgrounds of varying soil phosphorus supply. Climatic factors (temperature and precipitation) determined the initial reserve of total moisture in the soil when sowing oil flax, which was at the level of 82% of the lowest moisture capacity in a meter layer and did not depend on the background phosphorus supply. Mineral fertilizers increased crop productivity. Its highest yield was observed against the background of an increased supply of soil with mobile phosphorus (1.71 t/ha) with the pre-sowing application of ammonium nitrate and ammophos. The oil content of flax, on the contrary, decreased when using fertilizers. Its highest indicators (39.5%) were observed against background II when using phosphorus fertilizers.

Decoding comparative taste and nutrition regulation in Chinese cabbage via integrated metabolome and transcriptome analysis

Chinese cabbage (Brassica rapa L. ssp. pekinensis) is a widely consumed leafy vegetable known for its various health-beneficial nutrients. Caixin (ET and JY) represent distinct cultivars of Chinese cabbage that exhibit differential consumer preference attributed to variations in taste and nutritional content, with ET being characterized as sweeter and more nutritionally superior compared to JY. However, limited research has been conducted to explore regulation of flavor and nutrition-related quality traits in Chinese cabbage. In this pioneer study, comprehensive trans-meta-analysis was used to compare the metabolic and molecular underpinnings behind unique taste and nutritional profiles of ET and JY. 8-Methylsulfonyloctyl glucosinolates and Uridine 5′-diphospho-D-glucose exhibited the highest correlation coefficient in Pearson meta–meta-association, which modulate flavor and nutrition processes. While DAMs primarily featured L-Homomethionine, saccharic acid, 1,6-Di-O-caffeoyl-β-D-glucose, and Rutin, with notable variations in expression between ET and JY. Conspicuously, DEGs encoding structural enzymes i.e. Glucosinolates (MAM, CYP, UGT), flavonoids (CHS, CHI, F3H) and sucrose (SPS, SPP, SUS) synthases were identified as key players in nutrient and flavor production. Multi-omics conjoint analysis revealed that saccharides, amino acids, ascorbates, flavonoids, organic acids and vitamins were positively correlated with taste and nutrition, and were found to be overexpressed in ET. While aliphatic glucosinolates were abundant in JY compared to ET, they might play a critical role in regulating quality traits. Besides, HPLC and RT-qPCR corroborated multi-omics data reliability. These findings offer novel insights into the mechanisms governing the regulation of taste and nutritional levels in Chinese cabbage.

The effect of regular exercise combined with quantitative nutritional support on immune function indicators such as CD3+, CD4+, CD8+, and nutritional status in dialysis patients.

Abstract. To study the effect of regular exercise and quantitative nutri-tional support on dialysis patients’ immune function indicators and nutritional status, 100 uremic patients who underwent hemodialysis treatment in our hos-pital from February 2021 to February 2023 were selected as the study subjects. They were divided into a control group (n=50) that received regular exercise and routine nutritional support, and a research group (n=50) that received regular exercise and quantitative nutritional support. This study compared the baseline levels of nutritional indicators such as prealbumin (PA), transferrin (TF), serum albumin (SAB), and hemoglobin (HB); cellular immune indicators such as CD3+, CD4+, and CD8+; as well as humoral immune indicators such as immunoglobulin A (IgA), immunoglobulin G (IgG), and immunoglobulin M (IgM) at enrollment and after three months of intervention. At the time of enrollment, there were no significant differences in nutritional indicators be-tween the two groups of patients (p&gt;0.05), nor in the levels of cellular immune indicators (p&gt;0.05) or humoral immune indicators (p&gt;0.05). After three months of intervention, nutritional indicators such as PA in all patients in the experiment grew (p&lt;0.05), and those in the research group exceeded the con-trol group (p&lt;0.05). Similarly, the levels of CD3+ and other cellular immune indicators and the concentrations of IgA and other humoral immune indicators increased in both groups after three months of intervention (p&lt;0.05). Howev-er, these increases were higher in the research group than in the control group (p&lt;0.05). Regular exercise combined with quantitative nutritional support can effectively improve hemodialysis patients’ nutritional index levels, nutritional status, immune index levels, and immune function.
